Fun game for beginners right until the 4th boss, which is a frustrating roadblock. Until that point it always felt that you could just Get Better At Fangames to beat the levels, but that boss has a few too many hitpoints to be fun. Repeatedly dying to an unlucky projectile in the last 10% or so without feeling like you have any way of improving your skills to get past to the actual interesting part, the platforming, just isn't fun.
